IMPORTANT: The net amount of ride height increase depends upon the age & use of the vehicle,
wheel offset, & numerous other factors. Stated torsion bar ride height increases are based upon the
factory specifications. If the torsion bars were “cranked up” at some point in the past, expect a
corresponding reduction in overall height increase with the new torsion keys.
NOTE: The torsion bars, like any other spring, are subject to fatigue & sagging over time. Also,
torsion bars have different ratings depending on how the vehicle was equipped from the factory. In
some cases, installing heavier rated bars (which can be purchased from a Chevy / GMC dealer)
may be the only solution to regaining ride height lost from adding heavy aftermarket accessories,
such as a winch bumper or snow plow.
NOTE: Various types of torsion bar puller tools are available, however, due to the extreme loads
present in torsion bar suspension systems, we have found the two-jaw style tool that clamps to the
crossmember tends to slip & damage the crossmember. A C-clamp style puller tool is preferred &
available through various tool companies such as Snap-On,etc.
